LAWN-SPRINKLER.

SPECIFICATION formingpart of Letters Patent No. 515,625, dated February27, 1894.

Application led June Z, 18 93| Serial No. 476,356. (No model.)

To all whom, t may concern.-

Beit known that I, SAMUEL HOWARD Srofrfr, of Fullwood, in the county ot'Preston, England, have invented a new and Improved Lawu-Sprinkler, ofwhich the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved lawnsprinkler, which is simple and durable in construction, very efiectivein operation, conveniently cleaned, not liable to get clogged up, andarranged to finely divide the water and discharge the saine in sprays,covering the ground uni forrnly in a circular area of which thesupporting post is the center.

The invention is embodied in the construction and combination of partshereinafter described.

Reference is to be had to the accompanying drawings, forming a part ofthis speciiication, in which similar letters of reference indicatecorresponding parts in all the `figures.

Figure l is a side elevation of the improvement as applied. Fig. 2 isanl enlarged plan view of the same. Eig. 3 is a sectional side elevationof part of the improvement on the line 3-3 of Fig. 2. Eig 4 is auinverted plan view of the cover plate; and Fig. 5 is a plan View of thecup.

The improved lawn sprinkler is provided with a pipeA carrying at itslower end a T B supporting a coupling C, connected with the supply hoseI) leading from a suitable source of Water supply. The lower end of theT B is closed by a point or spade E arranged in alignment witlithe pipeAand adapted to be lforced into the ground so' as to support the pipe Ain a vertical position. See Fig. l.

On the upper end of the pipe A is screwed or otherwise secured, a cup Fformed with a beveled top edge F on which is adapted to be seated a likebeveled edge G', of a ilat cover plate G formed with an enlarged centralaperture through which passes a bolt H secured on a spider I, whose endsabut an annular shoulder formed in the interior of the cup.

On the outer end of the bolt H screws a hand nut J having an ornamentalshape and serving to hold the cover plate G with its beveled edge Gfirmly seated on the beveled edge F of the cup F. One of the twocontacting beveled edges F or G, is provided with radial grooves open atthe ends and closed at the open side by the opposite nongrooved bevelededge, so as to form jet apertures along the lines of the grooves for theexit of the water passing into the cup F from the pipe A under pressure.

'As illustrated in the drawings, the beveled edge F is the nou-groovedone, while in the beveled edge G of the cover plate G are formed theradial grooves G2, through which passes the water in jets as beforeexplained. In the cover plate G are also arranged angular dischargeopenings G3, each made with two concentric bores of which the inner boreis considerably larger in diameter than the outer bore, as plainly shownin Figs. 2, 3 and 4. This construction enables the water to dischargewith much greater force than if the bores were of uniform diameter.

Now, it will be seen that when the several parts are in the positionshown in Figs. l and 3, the cover plate G is firmly held to its seat onthe beveled edge F by the nut J screwing on the bolt H and abutting onthe top of the said cover plate. Now, when water under pressure passesthrough the hose D, coupling C, T B, into the pipe A and from the latterinto the cup F, then the water passes through the grooves G2 and theapertures G3 under considerable pressure, whereby the water is finelydivided into jets, of which the jets formed by the grooves G2 cover theground in a circle, while the individual jets of water passing throughthe apertures G3 are slightly inclined and come down onto the groundwithin the circle formed by the other jets passing through the groovesG2. ment the entire circular area around the pipe A is saturated withwater. By enlarging the inner bore of the openings G3, a water reservoiris formed i'or each opening, which insures a continuous passage of waterthrough the smaller outer bore of the opening under full pressure of thewater supply. It will be seen that by this arrangement the cover plate Gcan be readily removed by simply unscrewing the nut .I and lifting theplate off the bolt H, for conveniently cleaning the in- By this arrange-IOO terior of the cup F, the grooves G2 and open; ings G3, incase theyshould become clogged by sand or other impurities carried by the Water.

5 Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- In a lawn sprinkler, the combination ot' thecup, and its cover having correspondingly 1o beveled edges between whichare discharge openings, G2, the said cover being provided with an innercircle of apertures, G3, which are inclined at a less angle than saidopenings, and formed of two diereutial aligned bores, as shown anddescribed, to operate as l5 specified.
